UHP Water Blasting as a road marking removal technique. It is now the preferred road marking removal technique
UHP Water Blasting quickly removes markings faster and more thoroughly than abrasive methods – without damaging the pavement or asphalt. UHP Water blasting is fast and productive, and avoids exposing the environment to chemicals or contaminants. It also simplifies clean up, is dustless and leaves a clean surface.ean surface.
UHP Water Blasting uses water pressurised by an extremely powerful motor/pump to clean and remove markings from the pavement surface. These powerful motors can deliver pressure at the cleaning head of up to 40,000psi (2,700 bar).

The sheer force of the water delivered literally knocks the markings off the pavement. A vacuum recovery system removes all waste materials and surplus water leaving the road surface semi-dry.
Our UHP Water Blasting unit is mounted on a 26tonne truck and uses approx. 22 litres of water per minute (<5 gallons).

In the hands of our skilled and experienced operators, this process is capable of removing all kinds of road marking products without damaging the road surface. Our equipment is fitted with full dual controls thereby ensuring that all works are carried out in the same direction as the traffic flow.
The cleanliness of our UHP Water Blasting Removal System makes it a positive contributor to a healthier environment.


Road marking removal machine using high pressure water jetting road sign or airfied rubber.Present removal work for road markings has been time-consuming and labor intensive because it has been performed manually using shaving type equipment.

The traditional process causes traffic delay due to the passing control, resulting in unexpected accidents to workers working at dangerous road circumstance. Besides, the current shaving method leads to air pollution as well as explosive accidents caused by propane gas.

Thus, we have studied to develop the automatic removing equipment which consists of a high pressure water-jet system, automatic control system and mobile system: the water-jet system consists of an intensifier and nozzles to give a high pressure and spray on the marking;

The automatic control system is composed of one axis robot using a hydraulic servo actuator controlled by a lever; and the mobile system employs a truck which plays an important role for transport of equipment and forward movement in a removal process.

Traditional methods of road marking removal

Traditionally, road markings were removed through the process of burning. This is not only time-consuming, but dangerous through the release of smoke and fumes.

This method involves an industrial tool that exerts high temperatures to burn off the existing markings. Due to this hazardous process, there has been a need for an alternative method of road marking removal.

In this paper, we have analyzed the characteristics of road markings and investigated current removing methods in this field. In addition, we have organized and designed automatic removing equipment.

Road markings are laid onto roads with the intention of being permanent, and so the removal of them can be tricky. Old road markings have become a standard feature on roads, sometimes causing confusion to drivers.

Because of this, it is extremely important to have a method that effectively removes road markings, whilst doing so in a safe way to workers.

Water jetting road marking removal

Using water jets, the removal of road markings can be quick, easy, and efficient. Whether the road markings are red, white, yellow, or more, using a top of the range electronically controlled machine can remove the markings through propelling itself backwards and forwards.

This process does not involve any harsh chemicals or abrasives.Water jets can be used for the removal of road markings on a variety of surfaces, such as standard roads, airport runways and markings on school grounds.

Highway markings road marking removal machine introduced water blasting as a road marking removal equipment. It is now the preferred road marking removal technique by authorities .

Water blasting quickly removes markings faster and more thoroughly than abrasive methods – without damaging the pavement or asphalt. Water blasting is fast and productive, and avoids exposing the environment to chemicals or contaminants. It also simplifies clean up, is dustless and leaves a clean surface.

Water blasting uses high pressure by an extremely powerful motor/pump to clean and remove markings from the pavement surface. These powerful motors can deliver pressure at the cleaning head of up to 40,000psi (2,758bar).

Max safety technology for the road marking removal machine

  • Pump Overload Protection Technology

Relief valves are mounted on the boom cylinder counterbalance valves. These valves will release pressure in the event of excessive boom load to prevent damage to the boom.

  • Hopper Screen Interlock Technology

As an operator protection measure, the pump will automatically stop when the hopper screen is opened.

  • Hydraulic Oil Level Monitoring

The oil level in the hydraulic reservoir is continually monitored. If the level drops below a preset level, an alarm will sound and the pump will be stopped to prevent damage to the hydraulic system.
